Catnip is almost like a drug. It's like getting "high" but for cats. There's a particular chemical that triggers this reaction in their brains when they sniff it. However, it is not really known why it effects cats in the way it does, but it is due to a chemical called Nepetalactone that is released from the plant when a cat rubs, chews or otherwise "bruises" the leaves. Some cats aren't affected by catnip, and btw, some big cats are affected by it. It can also relieve stress and nervousness in cats.
